Default Mini fridge fermentation chamber

I just stared brewing a few weeks ago and quickly ran into some temperature control problems. I live in a small apartment and dont really have too much control over the temp (right now its in the mid 80s with all the windows open) so I decided to turn my old college mini fridge into a single carboy fermentation chamber.

I started with a 4 cubic foot Haier mini fridge.

Cut the shelves off the door and covered exposed insulation with foil tape.

I cut away the hump on the back that covers the compressor. Filled the void with foam insulation and covered in foil tape

In order to fit the carboy inside I had to unbolt the plate holding the compressor and set it back. Only two bolts hold it on now but no problems so far!

The thermostat thats in the fridge didnt allow me to keep the temperature warm enough for an ale so i had to use good old tape to fix the problem. I was able to tape the dial right before the fridge turned off and I am now able to keep the temperature around 65. Eventualy ill get a real temperature contoler so i can throw a lager in there.

I thought I would share my first homebrew diy project to see what you guys think.

Just added my ebay aquarium controller. bypassed the existing thermostat completely. The fridge plugs in to the outlet I wired in before the controller.

Cool build, haven't seen any one else actually cut out the compressor bump. I've been looking for a fridge that will hold a 6 gal better bottle for a while to deal with this.

I've been planning my fermentation chamber build, but I was thinking of building a collar for my fridge, instead of removing the hump, though I did like the concept.

How does the foil tape hold up in the fridge? Is it staying well? would you still recommend using it?

Unfortunately i have no idea what the model number is. This fridge has since been modified once again with a second temperature controlled chamber off the side and it would be quite a pain in the a$$ to get behind it to check as its a beast to move lol.

I did end up pulling the foil tape. It didn't hold up well with the condensation and was holding a ton of water between it and the insulation. I ended up using rubber spray sealer to cover it all up. Doesn't look pretty but it works!
